Children and adolescents with type 1 diabetes mellitus have a sixfold greater risk for prolonged QTc interval
Background: QT-wave abnormalities have been detected in type 1 diabetes mellitus (T1DM). Prolongation of the heart rate corrected QT interval (QTc) has been associated with cardiovascular mortality. We evaluated how often QT/QTc abnormalities are present in youth with T1DM and if they are associated with disease parameters. Methods: Sixty-two T1DM youngsters and equal age- and gender-matched controls were studied. Demographic, anthropometric, and laboratory data were determined. QT was measured on a 12-lead resting electrocardiogram. QTc was calculated using Bazett's formula. Results: T1DM patients had significantly longer QT/QTc than controls, but significance disappeared after adjustment for confounders. Abnormally prolonged QTc≥440 ms was observed six times more frequently in those with T1DM. QT was correlated with age, age at disease onset, but not with glycated hemoglobin or diabetes duration; QTc was only correlated with pubertal stage. Conclusions: T1DM youths have a sixfold increased risk for QT/QTc prolongation and should have regular follow-up for cardiac autonomic dysfunction. © 2014 by Walter de Gruyter Berlin Boston 2014
Evaluation of serum xenin and ghrelin levels and their relationship with nonalcoholic fatty liver disease and insulin resistance in obese adolescents
Aim Xenin is a peptide of the neurotensin/xenopsin/xenin family secreted from gastric cells and other tissues. The first aim of this study was to investigate the serum xenin and ghrelin levels in obese children and compare the patients with healthy controls. The second aim was to compare the xenin levels in patients with nonalcoholic fatty liver disease (NAFLD) and also with insulin resistance with the patients without these complications
